Root stomata in

Background and Aims: Stomata are specialized epidermal structures typically restricted to aerial organs of vascular plants. Their absence on roots has long been regarded as a general anatomical rule. Although rare reports in certain dicotyledonous taxa have described root stomata, these occurrences have been considered transient or developmentally anomalous. Within Apiaceae, no confirmed occurrence has previously been documented. This study aimed to investigate the anatomical presence of stomata on the primary roots of Methods: Seedlings of Key Results: Morphologically distinct stomata with characteristic guard cells were observed on the primary root. Their distribution was sparse and irregular. Root identity was supported by the overall anatomical organization of the examined sections, including a uniseriate epidermis and a broad parenchymatous cortex. Stomatal complexes were consistently detected across all examined accessions of the species. Conclusions: This study provides the first anatomically verified and reproducible report of stomata on the primary root of
